GLOBE-LIFTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 792,657, dated June 20, 1905.

Application filed April '7, 1905. Serial No. 254,337-

To all whom it may concern:

Be it known that I, JAMES H. HILL, a resident of Rochester, in the county of Monroe and State of New York, have invented cer tain new and useful Improvements in Globe- Lifting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to tubular-lanternglobe-lifting devices and to a class made of wire pivotally connected to the globe-plate and supported near each end in bearings at the sides of the air-tubes. Heretofore such lifting-wire has been provided at one end with a crank, handle, or thumb-piece, whereby it could be turned in its bearings to raise the globe-plate and globe, a spring being put under tension thereby. Retaining lugs or notches have been provided to hold the handle in its upper and lower positions. It is held in its upper position until such time as the globe is to be lowered, whereupon the handle being disengaged from the retaininglug by a horizontal pull the lobe is lowered by the return of the spring-lifter. Said handle and the main part of the lifter have been so formed and combined with the other parts that it could not be actuated without tipping the lantern on its base unless held, the use of both hands of the manipulator being required for the purpose, one to disengage the handle and the other to hold the lantern.

The object of my improvement is to provide a lifter for a globe that can be operated with one hand without destroying the stability of the lantern and the other hand of the operator left free for the striking of a match or other office.

The invention consists in the construction hereinafter described and ointed out.

In the accompanying rawings, forming part of this specification, Figure 1 is a partial side elevation of a tubular lantern. Fig. 2 is a similar view taken at right angles to the view in Fig. 1. Fig. 3 is a perspective. Figs. 4 and 5 are views of modified details.

Numeral 1 denotes the globe, and 2 the globe-plate. Said plate is provided with a bearing 3 for a globe-lifting wire 4. This wire is slightly bent at 5 on each side of the bearing 3 and extends to near the lanterntubes 6, where it is provided with verticallyextending cranks or bends 7.

8 denotes portions of the lifter situated in bearings 9, fixed to the lantern-tubes. These parts 8 are by preference parallel to the vertical plane passing centrally through the tubes and globe.

10 denotes a portion of the wire disposed substantially at right angles to the contiguous part 8.

11 denotes a part of the wire having a ring or thumb-piece 12. This part 11 is closely adjacent a tube 6 and parallel therewith, the bend at 13 being substantially at right angles with the part 10.

14 denotes a lug fixed to tube 6 and having an inclined edge terminating in a slot 15 at its lower end, furnishing a wire-engaging shoulder 16.

To lift the globe, the part 11 is depressed in manner to slide the part 10 down to a point below the shoulder 15. This turns the parts 8 in their bearings on the tubes and also turns the wire in its bearings 3 beneath the globe-plate, with the effect to lift the globe and put the lifter under compression. It is held against return by its engagement under the shoulder 15. As the lug 14 has no shoulder at its upper end, a downward pressure on the lifter-handle suflicient to move the part 10 down the incline automatically forces or draws the lifter endwise sufficient to ermit its engagement under shoulder 15, it eing unnecessary to hold the lantern against a horizontal pull on the lifter, as

' would be required if it were engaged by a shoulder or in a notch at the upper end of the lug, as in prior constructions.

Instead of a slot 15, as represented a simple shoulderZlG, as shown, may be employed.

The friction of the lifter in its bearings and its torsional resistance are suflicient in the form herein shown and described to prevent the accidental operation of the lifter; but, if desired, to further insure stability the han- 1 having a shoulder at its lower end, said incline disappearing at the tube to avoid a shoulder at its'upper, end, all substantially as set forth, whereby the lifter can be actuated with one hand and without holding the lantern.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
